Service behaviour of bulls of different breeds under uniform management conditions

Indian Journal of Animal Reproduction 9(2): 109-114

Five Holstein, 5 Jersey and 5 crossbred Holstein bulls and 5 Murrah buffalo bulls were scored during semen collection on a scale of 0-4 (0 = no response) for sexual interest, erection, protrusion of the penis, mounting, reaction time, body position, type of seeking and ejaculation.
